Deferred proposals

These proposal are no longer being actively considered but could potentially be revived in the future:

• let expressions
• types
• syntax for efficient traits (markm)
• shallow continuations, a simple and general form for capturing a single function activation (dherman, brendan)
• byte arrays, based on emerging webapi discussions and implementations
• Proxies:
  • proxy instanceof, enabling proxies to trap instanceof directly. (tomvc, markm)
  • stopTrapping, enabling direct proxies to be “switched off” (tomvc, markm)
• Specification Techniques
  • specification language, using Harmony to describe Harmony.
  • Another alternative, translating the ES5 spec. into a JavaScript-based definitional interpreter es5definterp.js.txt
  • narrowing_chapter_16 (markm)
